(Redirected from GSC bit)
 | This article needs to be updated. (February 2023) |
This is a list of MobileGestalt keys supported by iOS. Prior to iOS 6.0, this was handled by GraphicsServices, and values were retrieved from model definition files. Starting with iOS 7.0, the keys moved to the DeviceTree. Keys that existed prior to iOS 7.0 can be retrieved via the equivalent GraphicsServices functions.
Due to the original name, these keys may also be referred to as GSCs: GraphicServices Capabilities.
